Mooresville, N.C.-based Lowe's is making a big shift in its in-store work force, favoring part-timers over middle managers.

The move will cut about 1,700 middle management jobs in the stores, but will lead to an additional 8,000 to 10,000 part-time workers, according to Chris Ahearn, Lowe's VP public relations. The shakeup is expected to take effect Jan. 29.
